To ALL ressorts 'ro wHoM THESE PRESENTS sHALLfcoME;

Be it known that l', MILO S. BURR, of Boston, in the county of Suffolk, and State ot' Massachusetts, have made certain newand useful improvements having reference to' Nursing-Bottles; und I dohereby declare the following tobc a full, clear, and exact description thereof', reference being hud to thc 'accompanying drawings, making a part thereof. Of the said drawingsi Figure 1 .denotes a side elevation of anursing-hottle provided with my invention or improvements.

` Figure 2 is a top view of the bottle-stopper,y andV Figure 3 a vertical `section of'it. i

Figure 4 is tt section'ofthe combined mouth-guard and nipple and tube-connector.

Figure 5 is a view of a portion ofthe elastic tube, the mouth-guard and connector, with an ordinary nipple applied to its auxiliary shoulder. I The object of my invention is to'remedy certain defects incident to nursing-bottles as ordinarily constructed,I

In the -said drawings, denotes an ordinary glass bottle provided with a tubular stopper, B, and having a flexible India-rubber tube, C, extending upfrom the interior of the bottle 'or milk-reservoir, and going axially through a cylindrical hole made through the said stopper, andb'eing connected at its outer end to one end .of an annular flanged connection-piece, E. To the opposite end of the connector an India-rubberinipple, D, is atlixed. F-is the mouth-guard combined .with the nipple and tube-connector, as hereinafter described. It is a fact well known to those conversant with the art to which myrinvention appertains that much diiculty has been experienced with the Stoppers of nursing-bottles as ordinarily constructed, that is, with the cap ot' the stopper made o f a wooden button or disk. and the entire shank'of cork, such shank being glued tothe bottom of the i cap or in a socket made therein. Owing to the necessity of the frequent insertion in and withdrawal of the stopper from the mouth of the bottle, the shank of the stopper (fitting, as it must do, tightly to the neck of the bottlelhas often been disconnected or torn from thecap portion,`avnd thereby thel bottle rendered useless. To obviate this diHiculty'I formthe'cap a of the stopper of some hard wood or other suitable materia-l, and with a hollow cylindrical shank, b, to extend down through the cork or othcrelastic packing, c, als shown in fig. 3, the said cork or packing being glued or cemented to said cap and shank. This peculiar formation of the stopper makes it a. very strong, effective, and durable one. 'The outer end of the exible tube() I uiix to one extremity of a wooden or other suitable connection-piece, E, andto the other extremity I attach thenipple D, as seen in .20, tig. 1. Instead of making this connection-piece as a plain cylinder, and with an annular shoulderon each of its ends, and forming the vmouth-guard in a separate piece, I construct the said connection-piece and the mouth-guard or shield F, in one piece, such shield being to rest against the lips of a child, and to maintain the nipple in its proper position in its mouth. This combined guard and connector I also form with two annular shoulders, c d, on or near its outer end,as seen in tig. 4. `One of these shoulders, viz, 01,1 make-of about double the diameter of the other, iniorder that incase the nipple-belonging to the bottle should be lost or rendered unfit foruse, and another of the kindveould not he had, -one of the vordinary form, as shown in g. 5, could bo applied to the shoulder d. This peculiar construction ofthe connection-piece E, viz, with the mouth-guard and the auxiliary shoulder d in one piece, possesses several important advantages,'as it not only prevents the guard from being lost oii` the nipple or tlexible tube, but retains it always in its proper position. It also oftentimes renders the bottle available when under other circumstances st lehfwould not be the case. To the lower endof the said flexible tube C, or the. part thereof` which projects below the stopper B, I attach a glass tube, and, disposed aroundits lower end, a narrow, annulus of rubber, thcsame being for the purpose of preventing breakage ofthe lower end of the glass tube by striking against the interior surfaceof the bottle. The diameter of the elastic tube C should be equal to or a little greater than that of the hole made through the stopper, `order that there may be a perfectly tight joint between the two. Furthermore, the said flexible tube should be so applied lto the said stopper as to be capable of being movedv up or down within thc same, in order to adjust the end of the glass tube-at a proper distance from the bottom of the bottle.

Having described my improved nursing-bottle, what Iiclaim therein is as follows:

I claim themouth-guard, the tube, and nipple-connection combined, or made of one piece of wood or other suitable material, as set forth.

I also claim the tube and nipple-connectioniE, provided with the auxiliary shoulder d, as and for the purpose set forth.
